Dr. Vinod Kumar is an Associate Professor (Senior Lecturer) in Renewable Energy and Coordinator of the MSc Renewable Energy Technology (RENT) Programme in the Department of Physics at The University of the West Indies, St. Augustine, Trinidad and Tobago. He previously held research and academic positions at DaDU (Ethiopia), Indian Institute of Technology Delhi (India), ICCF-UCA (France), University of Tulsa (USA), University of the Free State (South Africa), and Inter-University Accelerator Centre New Delhi (India). Dr. Vinod Kumar received his MSc and PhD degrees in Physics from Gurukula Kangri (Deemed to be University), Haridwar, Uttarakhand, India. Dr. Kumar has published more than 160 research articles in reputed international journals, with over 8,300 citations and an h-index of 51. He has been granted one patent and has published four books and several book chapters. He has supervised many UG and PG students and has organized several national and international conferences. His research interests include the design and application of nanomaterials for renewable energy and environmental sustainability, especially in third-generation solar cells, photocatalysis, solar energy conversion, optoelectronic devices, solid-state lighting, and energy harvesting.  

Dr. Arvind Kumar obtained his M.Sc. degree in Physics from Hemwati Nandan Bahuguna Garhwal University, India, followed by a Ph.D. degree in Physics from the Bhabha Atomic Research Centre under the aegis of the Homi Bhabha National Institute, Mumbai, India. Later, he worked at the CSIR-National Aerospace Laboratories, Bangalore, India where he was involved in the fabrication of nanoporous surfaces for solar energy applications, transparent electrodes, and 1D hybrid-interface-based photodetectors. Presently, he is an Assistant Professor at Chaman Lal (P.G.) College (Uttarakhand Higher Education), India, with 10 years of rich research and teaching experience. He was also selected for a scientist position at C-MET, Pune (Ministry of Electronics and Information Technology) India in December 2017. His current research focuses on hybrid nanomaterials, low-powered chemiresistive sensors for environmental monitoring, photodetectors, and energy devices. To his credit, he has published 30 research articles in reputed journals, served as an editor for one book, contributed two book chapters, and holds two granted patents.
